KLIMEK, OF EAST RUTHERFORD, NEW JERSEY, ASSIGNORTO TURBINE PATENTS CORPORATION, OF NEW YORK, Y., A CORPORATION OFDELAWARE HYDRAULIC rowan TRANSMITTER Application filed- June 19,

The present invention relates to improvements in hydraulictransmissions, and more particularly it pertains to such devices asemploy a fluid impelling member, a fluld 1m-- pelled member in the formof a turbine rotor,

engages with the vanes or blades of the turbine rotor, and setting uprotary movement thereof transmits therethrough the power of a primemover to suitable apparatus to be driven.

To permit of continuous rotation of the prime mover and the fluidimpelling member without operation of the fluid turbine rotor the fluidcouple between the two is rendered inefli'ective. This has beenaccomplished in various ways in the art but for various reasons theyhave not proven highly efiicient.

It is one of the objects of the present invention to provide a new andimproved construction whereby the fluid couple between a fluid impellingmember and a fluid impelled turbine rotor may be rendered inefl'ective,which construction will be highly efficient in its operation.

It is a further object of the invention to provide a new and improvedhydraulic power transmitter in which a driving member may remain idleduring continued operation of a driven member without employingmechanieal clutches and similar devices.

It is a further object of the invention to so construct a device of theaforementioned character that when the fluid couple is renderedineffective, the fluid impelled member ,will not be subjected to drag asis customary in devices of this type.

Other objects of the invention relate to certain novel andimprovedarrangements and 1929. Serial No- 372,086.

The invention as herein illustrated comprises a driving member 10 and adriven member 11. The driving member is suitably secured to the shaft12v of a suitable prime mover, not shown, and the driving member in theherein illustrated embodiment of the invention preferably constitutes.the flywheel of the said prime mover.

The driven member llis keyed to a shaft 13 suitably connected to themechanism to be driven and not herein shown. That end 14 of the shaft 13which occupies a position closely adjacent the. driving member 16, ispreferably supported in a hearing such as 15 WlllOh bearing is carriedby the said driving member 10. l

The driven member 11 operates within a suitable housing carried by, androtatable I with the driving member 10. As herein illustrated thishousing consists of two parts designated 16 and 17 suitably securedtogether and to the driving member preferably by the same meanssuch ascap screws 18. The

member 16 of the housing preferably nests within the driving mem'ber'lOwhich is recessed as at 19 to accommodate said housing member 16. Thishousing member also preferably encloses the end 14 of the shaft 13, andthe bearing in which it .is mounted as here tofore described. To providefor rotatably mounting the housing member 17 upon the shaft 13 saidhousing member 17 may be se-.

. ing placed under compression by a collar 26 and a-coil spring 27, oneend of which abuts the sleeve 28 which serves to close the open end ofthe sleeve extension 23. This sleeve 23 is retained in position by alock bolt or the like 29 as shown in Fig. 1. The housing -member 17carries a plurality of spaced partitions or walls 30 secured thereto inany desired manner as at 31, these walls being secured at theiropposite'sides asbybenttongues 32, see Fig. 5, to an annular member 33the cross-sectional form of which is shown in Fig. 1. The lower ends ofthese partitions 30 are designated by the reference numeral 34 andoccupy a position adjacent the flanged bearing member 21 of the housing.These partitions 30 provide a plurality of passages 35, the inner endsof which form the inlets therefor. The outlet ends of the passages 35are designated bythe reference numeral 36, see Fig. 1, and it will benoted thatthese outlets are disposed radially of the driven memher, thepurpose of whichwill be hereinafter described.

The driven member preferably comprises a main body portion 40 having aflanged portion 41, and the diameter of this driven member is suchthatthe peripheral edge of the flanged portion thereof occupies aposition in close relation to theoutlet ends 36 of the passages 35. 6 Anannular member is carried by the driven member, in spaced relation tothe flanged portion 41 thereof, by means of rivets or studs 45a, and inthe space between the parts 45 and 41 there are a plurality of vanes orblades 46 and a plurality of connect ing studs or rivets.

These vanes or blades, as shown in Fig. 5, are each carried upon abearing member 47,, each end of which is rounded as at 48 and 49 toprovide for pivotally or rotatably mountmg the blades in the parts 41and 45 respectively. The blades 46 divide the space between the flangedportion 41 of the driven member, and the annular member 45' into aplurality of radially extending passages 50, the inlet ends of which arejuxtaposed to the outlet ends 36 of the passages 35, while the outletends of these passages 50 are juxtaposed to the inlet ends of thepassages 35. Thus if the housing or casing is filled with a suit-ableliquid, upon rotation of the driving member, the said liquid will becaused to 7 move through the passages 35 and 50 in the direction of thearrow in Fig. 1, and that if the vanes or blades 46 are in the positionin which they are shown in Fig. 2, rotary movement of'the driven member11, and a driving of the shaft 13 will result.

To provide for'free rotation of the driving member 10 without impartinga driving force to the driven member 11, the vanes of blades are adaptedto be moved to the position in which they are shown in Fig. 3. For thispurpose, each of the bearing members 47 of the vanes or blades 46 isprovided upon its end 49 with a plate 55, see Figs. 2 and 3, and eachplate carries a crank 0r eccentrically positioned pin 56. Each pin 56 isreceived in its respective cam slot 57 in an annular member 58. Theannular member 45 is flanged as at 59 to form a support for thecam-slotted annular member 58, and also the bearing about which itturns. It will thus be seen that as the cam-slotted member 58 isrotated, the cam slots 57 thereof operating upon the eccentric pins orcranks 56. will rock the bearing members 47 of the vanes or blades 46 toposition said vanes o'r blades in either their operative or inoperativeposition. The plate on the end of the bearing member 47 has. a cam facewhich engages the inner sidet'pf the outer flange of the annular member58, see Fig. 2, thereby locking vanes 46 against rotation when they areunder full fluid engagementl The cam slot 57 has a straight portionwhich will allow the plate 55 to disengage from the annular member 58when said member is rotated through the shaft 61 in order to ,bring thedriven member into an inoperative position.

The cam slotted annular member 58 is rotated by means of a gear 60mounted upon said shaft 61, which gear meshes with a segmental gear 62carried by the cam-slotted member 58, and thus each time the shaft 61 isrotated, through the medium of the gear 60 and the segmental gear 62,said camslotted annular member will be rotated.

movement upon the member 21 of the driv-' ing member by rods or the-like71, and the antifriction bearing member 67 of the shaft 61 travels inthe peripheral channel of this surround the rods 71 and exert theirforce to maintain the. channeled annular-member in the position in whichit is shown in Fig. 1, in which position, the shaft 61 through themedium of the gears 60 and 62 andthe cam-slotted annular member 58position the vanes or blades 46 in the operative position in which theyare shown in Fig. 2.

, If the channeled member 70 be moved to the right in Fig. 1, the shaft61 will operate the gear 60 which in turn will operate the cam-slottedannular member 58 to move the vanes or blades to their inoperativeposition, in which position they are shown in Fig. 3.

' For moving the member 70 to the right in Fig. 1, driving rods mountedin stufling boxes 81 in the bearing member 2'1 of the driving member areprovided. These driving rods 80 are connectedto a suitable bearingmember 85 as at 86, and said bearing member 85 is slidably mounted uponthe sleeve extension 23 of the driving member 10.

The reference numeral designates arock shaft operated manually in anydesired manner, and said rock shaft is connected by suitable-linkage 91only partially herein shown.

to the bearing member 85 in such a manner that each time the rock shaft90 is moved in an anticlockwise direction, the bearing member 85 willlikewise be moved to the right to opcrate the driving rods 80 and thevanes or blades 46 in the manner heretofore described,

Means is provided for intercepting the floW of fluid when the vanes orblades 46 are moved to their inoperative position, and this meanspreferably comprises a barrier or wall mount ed for movement across thedischarge 'end 36' of the passages 35. In the. present embodiment of theinvention, this means for intercepting the movement or flow of the fluidis preferably operated by the same means as employed for operating thevanes or blades 46 and is preferably operated simultaneously with theoperation thereof.

As shown in Fig. 1, the means emploved V for intercepting the flow offluid through the passages 35 and 50. consists of an annular member 92snugly fitted within the annular member 33 when the vanes or blades 46are in their operative position as shown in 1. Carried by the annularmember 92 upon' the inner circumference thereof, there is a I channeledmember-93 and operating in said channeled member 93 there is a crank 94,which crank is carried by. the upper end of the shaft 61 and is operatedthereby each time the shaft is operated.- The crank 94 may be providedwith an antifriction bearing member for engagement within the channeledmember 93, and as shown herein, this antifriction member is preferablyspherical in form and of such dimension that it engages the inner facesof the side walls of said channeled "member 93; annular member 70.Springs 72 preferably From the foregoing, it will be apparent that eachtime the shaft 61 is operated as heretofore described to effect anoperation of the 4 vanes or blades, the annular member 92 will besimultaneously operated to intercept the flow of fluid through thepassages 35 and 50. For'example, with the several parts in the positionin which they are shown in Fig. 1, if the shaft 61 be rotated to movethe vanes or blades 46 to their inoperative position,

through the medium of the crank 94, the annnlar member. 92 will besimultaneously .moved toposition across the discharge ends 36 of thepassages 35 to intercept the'flow of fluid through the passages 35 and50. in which position it is shown in Fig. 4 of the drawings.

In the construction above described the vanes or blades 46 are thin,curved plates which, when in closed position, overlap as shown at theleft hand side of Fig.3. In

' Figs. 6 and 7 I have shown blades 46a which are somewhat thicker andshorter, but the ends are beveled so that when the blades are moved toclosed position as shown in Fig. 6 the beveled ends engage to form asubstantially smooth, cylindrical, outer surface.

While the invention is herein embodied in a preferred form,,it will beunderstood that it is not limited to that form in which it isillustrated, and that it may be developed in various other forms whichrightfully fall within the purview of the appended claims.
